Adam and Eve was Klimt's first biblical painting. Certainly it was the only one to present humankind in a state of grace, for the scene would seem to be set before the Fall, perhaps at the moment of Eve's creation. As the sole truly chaste woman, Eve is a heroine very different from Judith.
Klimt's contemporaries remarked that his ideal woman generally departed significantly from the Viennese notion of beauty: she was slender rather than buxom, redhaired or brunette rather than blond. This "Old Testament type" (as Klimt's typical heroine was euphemistically called) had an aura of exoticism that was both appealing and intentionally frightening.
A sword that cut both ways, his conception of the femmefatale indulged latent anti-Semitic fears while at the same time glorifying the very subject of those fears. It is not surprising that, for this reason (and because many of his patrons were Jewish), Klimt was subject to anti-Semitic attacks. Be that as it may, it is curious to note that when he chose his model for the mother of the human race, he picked a blond, "pure-blooded Aryan" type - one of the few to appear in his paintings.
